So my Active Directory setup is set to work for computers running Vista or higher. I didn't foresee the need to have a Windows Server 2003 computer on the domain, so how can I now be able to join the 2003 computer to the 2008 domain? Thanks

You can just join it to the domain. The domain functional level is only for the versions of Windows that can be domain controllers on the domain. You could join a Windows NT 4 machine to the domain if you wanted to.
